Eight Lepiota species with a hymeniform pileus covering that are known in California are presented and discussed. Lepiota phaeoderma is described as new; this species is characterized by a dark pileus surface, which splits open into small patches around the umbo, and the absence of an annulus. Lepiota neophana, a species with an annulus and a closed brown pileus surface, and L. lilacea, with a ...

Species in the mushroom genus Lepiota can cause fatal mushroom poisonings due to their content of amatoxins such as α-amanitin. Previous studies of the toxin composition of poisonous Lepiota species relied on analytical methods of low sensitivity or resolution. Using liquid chromatography coupled to UV absorbance and mass spectrometry, we analyzed the spectrum of peptide toxins present in six I...

in the framework of the collection and identification of agaric fungi of iran, three species of the genus lepiota, viz. lepiota brunneoincarnata, l. echinella and l. subincarnata are reported as new records for mycobiota of iran. two species, l. brunneoincarnata and l. subincarnata are deadly poisonous taxa. up to now, two species of amanita, a. phalloides and a. verna, and one from galerina, g...

We report the case of a collective intoxication by ingestion of a mushroom “Lepiota brunneoincarnata” at the origin of the death of four members of the same family aged between 3 and 15 year old. We discuss the physiopathology and the prognosis factors of such intoxications through these four observations which highlight the clinical signs, biological disturbances due to the intoxication, autop...
